+pusha/popa family generates incorrect code
+Noticed in https://github.com/FEX-Emu/FEX/pull/4585 that these family of instructions are moving the SP to a temporary register and doing push/pop operations on the temporary and then moving the SP set to the end.
+
+If an async signal landed in the middle of that instruction then Linux async signal handling would corrupt the guest stack since it assumes correct guest SP at all times.
